10 allwhom t may cnccrn: Y Y Y Be it known that l, FREDERICK 1V. Mo- NrorroL, subject of the lring of Great Britain, residing at St. (lohn, Province of New Brunswick, Canada, have invented certain new and useful llmprovements in Sheet- Holding Attachments for ll/lusic -Racks; and l do hereby declare that the following is a full, clear, and enact description of the invention, such as will enable others skilled in the art to whichA it appertains to make and use the same.

rlhe present invention relates to sheet holding attachments for music racks, forsecurely holding in view of the performer the sheets of music he is playing. y

The principal obj ect of the invention is to provide an attachment adapted for connection to music rack, that will hold the `music sheets in such manner as to permit of the unobstructed view of the same and which is particularly arranged for usel for out-door playing. l

Another object of the invention is to pro vide a device, which is capable of adjustment for the holding of music sheets of diversified sizes and which is provided with movable spring-actuated clamping means, for the upper edge of the music sheet.

Tvl/Tith the above and other objects in View which will hereinaftVerV appear as. the"description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

1n the accompanying drawings has been shown a simplevand preferred form of the invention, it being, however understood that no limitation is necessarily made to the precise structural details herein exhibited, but

the right is hereby reserved to any changes, alterations or modifications to which rc- Y course may be had that come within'the scope of the claims without departing from the spirit of the invention or sacrificing the efficiency of the same.

lFig. 6y is a magnified elevation of the center barand pawlmembers; 1 Fig. Z is a detail view ofthe building cord and center holding clip; and, i F ig. 8 is a. perspective viewrof one of the clipsdetached from the device.

Referring vto the P reference, 1 designates the frame ofthe music rack which is supported by aU suitable standard 2 provided with feet, not" illustrated.

vThe attachment comprises"v a" relatively fiat central bar 3 the rear lowerl face of which is attached by meansof the rivets 4 to the strap 'braclretftl This'bracket. 5 is formed with anofiset portion 6 which latter isk spacedV fromA the bar 3, though it `extends in parallel plane therewith. he offset por.-

tion; ofrbraclret on'its louter surface is formed, with studs 7 and S which together with the offset portion lare-apertured for the reception of the wingbolts) and `10. These bolts 9 and 10 when adjusted servelto hold the bar 3 upon themusic rack 1.

Mounted on the pivot pins 11 and 12 vaCljacent, 'the lower end of the central bark 3,

are the arms 13 and 14 which are connected ngures by V:numerals vof by the pivot pins 15 and 16 to the outer arms 17 and 18. vThese arms 1,7v and18 have connectedto their free ends by.mean's of the` pins 19l and.; V20, .thev angle members 21 and 22 which carry the sheet holding clips which will now be described. The anglemember's 21 and 22 are capable of pivotal adjustment of their respective pin connections 19 and 20 and the horizontal leg portions 23 of the angle members 21 and 22 are formed with openings 24 in which are mounted the clips 25 formedof spring metal. T he clips 25 are of cruciform construction and the head por#A tions 26 extend Aat right anglesto the body portion of the clips.. Thishead 'portion is bent over at a slight angle and when the clip body'portions are passed through the I Y angle member openings. 24, the head portions 26 engage the upper surface of the horizontal leg portions 23 of V'said angle members, whereby the said clips 25 are held in position. In this manner the clips 25 are not only held in position upon the angle l' members 21, but they are likewise resultant of .such mounting, capable of limited pivotal adjustment thereupon. V'The blade springs 27 .are riveted as at 28 to the horizontal leg portion 23 ofthe langle members21 andk these freeends engage the head portions 26 of the clips 25, serving to tension the body portions of the saineV downwardly against the lower leg portions 29 of the angle members 21. The outer ends 30 of the clips 25 are upwardly bowed and when the device is in position upon the music rack, the music sheet has its upper edge portion disposed against the outer surface of the lower leg portions 29 of theangle members 21 and beneath the body portion of the clips 25.

The arms 13 and ltare formed with the rack teeth 31 and 32, and connected to the lower end ofthe central bar 3 upon the pivot pins 33 are the'angularly disposed pawl members 34 and V35. These pawl members 34E Aand 35 are formed with chisel ends which-,engage the rack teeth 31 and 32 whereby Vthe arms 13, 14,17 and 1S are held in position. Y

In this manner these arms 13, 14:, 17 and i8 are capable of adjustment for different sizes of the music sheets. .K

An elastic cord 3? has one end secured to the upper part of the central bar 3 while its lower end is attached to the angle clip 38. The elastic cord 37,v after the musicV sheet has been' inserted under the clips 25, is drawn across the said sheet at its central partand the angle clip 38 engages the music frame bar 39, which serves to hold the cord 37 taut and resultantly the music sheet is held in position. t

It is obvious that in this manner the music sheet may be quickly adjusted lupon the rack and held in vposition so that the leaves willrnot become deranged or blown OH". i The device may be quickly detached from the music stand or rack by the adjustment of the wing bolts 9 and l0 and the attach ment may be folded up for insertion into the pocket or into the instrument-case with the toldable rack.4

Having thus fully' described my invention, what I claim as new and desire to secure by Letters Patent is l. The combination with a music rack, of av music sheet holding device comprising .a central bar member adapted for detachable connection toV said central bar, a -pair of arms pivotally connected to said bar member, a pair of arms pivotally mounted on the free ends of the first mentioned bars, spring clips (arranged on the second mentioned bars,

vthe iirst mentioned bars formed withrack teeth, a pair of pawl members pivotally connected to the bar member, and said pawl members adapted for engagement withthe rack teeth for holding said arms in adjusted position. 1 v
